I think... I think I've delayed long enough.
Vulcan is in terrible shape =/

This ... thing has been growing on his for months. No medication I use works, and no amount of TLC has made any difference. I've tried delaying, hoping that time will help, but I just don't see any way time will help.
I'm asking for some way of humane euthanization. I may or may not use it, but I'm thinking so. With the way he is, he's not going to die soon, and that stuff will just keep taking him over. He's really got no joy in his life. His swimming is hindered, and he can't have any plants and such in his tanks, due to his water changes.
I don't think my mind can be changed now. It'll kill me to do it, but I feel like it's better for him if I do.
Besides, it's killing me more to see him like this than it would to just... end it all.

euthenasia:Clove Oil & Vodka
1. Add tank water to a measuring cup or other container. Measure the amount of tank water you add to the cup or container and make a note of it. Place the fish in the container. If the fish is in a clear container, place a dark towel around it to calm the fish.

2. Fill a small, clean jar or bottle with tank water, leaving some room at the top. This might be a baby food jar or pill bottle. Put 1 drop of clove oil in the jar or bottle, cap and shake vigorously. The clove oil must emulsify, turning the water milky white.

3. Gently pour about 1/4 of this emulsified mixture into the fish's container. The fish will begin to fall asleep. Let the fish be for about 10 minutes. The fish should be resting on the bottom by then. It will look dead, but if you watch closely its gills will be breathing once every few seconds. If after 10 minutes the fish is still rising off the bottom swimming intermittently, retrieve the jar or bottle of emulsified clove oil, re-shake, and add the same dose to the fish's container. Wait again.

4. Once the fish is asleep on the bottom, add 20-25% white grain alcohol such as vodka. For example, if the fish is in 8oz of water, add 2oz of vodka. Let the fish stay there for at least 20 minutes.

5. Check the fish carefully after 20 minutes for any gill movement. If there is no gill movement over a 60 second period, the fish has expired.

I am sooo sorry about Vulcan! He is such a pretty fish. I know how hard this is for you. You do whatever you feel you need to do. He is a very lucky boy to have an owner who loves him so much and cares so much for his well being. I know you tried everything you could to make him better. I'm sorry things didn't work out. You gave him the best of care and I'm sure that, somehow, he knows that you did your best for him and that you love him so much.

I've used salt baths, maracyn 1, maracyn 2, bettafix, melafix, and jfe. I tired the betta and mela fix just in case, but it was a no go ):
Thanks for the info. I'll pick up the stuff tomorrow. If I can't do it, I'll ask for my mom's help.
